If I were to add a zane thang to my 8 n would my lift capacity increase? I was hoping that with there would be an increase.

a zane thang is an ADJUSTMENT jig. it will simply allow you to set it to the correct values for working within range of movement.
lift force will be a function of pressure and piston/cyl bore.
if you don't increase either.. you gain nothing.
even if you plumbed in a live thang pump, the piston changes none.. and the oem lift relief valve is still in place.. so you can't gain anything there either with respect to lifting force, you might change geometry a bit to gian lift force and loose lift height.. but that is a seperate issue.
no free meal..it's all physics....

Maybe yes, maybe no.
If you are hoping to make it pick up more than Ford designed it to the answer is no. The designed lift capacity is determined by the diameter of the lift piston, the hydraulic pump pressure, and the geometry of the lift linkage. The hydraulic pressure is limited to 1600 PSI by the internal OEM safety relief valve so even if you add a second pump that produces a higher pressure the lift cylinder will never see it.
On the other hand if your lift is weak and you are getting less than the designed lift capacity because your internal pump is worn and isn't producing 1600 PSI pressure an external pump will make up the difference. In that case an external pump is a good way to restore the lift back to it's designed lift capacity.

when I said zane thang i meant the live hydra pump. Does help with lifting force?

a zane thang won't increase any flow...

3 times now.. NO!
unless your pump is so worn out that it won't make proper flow or pressure.
if your relief is weak then even adding an external pump won't help.
if the cyl rings or the bore is bad it's a leaker.. etc..etc.
are you asking it to do too much.. or wanting a machine that lifts more than the N was designed for?

We are talkning about a LiveThang. It can and does increase flow but it can't and won't increase max system working pressure.

Zane Thang or Zane's Live Thang?
The Zane Thang adds position control to a 9N/2N that an 8N already has.
If you're talking about the Live Thang, what are you trying to lift?
A correctly functioning lift will lift enough to pull your front tires off the ground.

he said a zane thang.. not a live thang.
just saying.

Not asking for too much lift just a 4X5 bale of hay(it used to do it). It has a frontend loader and the bale of hay on the rear balances the tractor real nice. It struggles on the last cutting of hay, it will not hold when I put it in gear, so I know it is starting to have problems.

Don't forget that all 4x5 bales are not created equal. The machine settings, windrows, density, moisture of material can result in bales of very widely varying weights. Having said that, sure these old tractors wear out & pumps can produce lower output, reliefs can't begin to relieve at lower pressures, leaks develop, etc. Chain lift arms down & read pressure at lift test port.

Wouldn't you rather just wildly speculate - it's so much more fun

Yes, when the boards have been so devoid of real problems to solve as they have been lately, it helps keep up the traffic & I'm sure YT appreciates that.
